Bank Routing Number

Bank routing number or routing transit number (RTN) is a nine digit number used to identify a financial institution in a transaction. Most common types of transaction being ACH and wire transfers. Some banks and credit unions may have multiple routing numbers serving different purposes, geographical regions or branches. Routing numbers are printed on the bottom of a check. A bank's Routing Transit Number (also known as an RTN or ABA Routing Number), is a 9-digit code assigned to all banks in the United States by the American Bankers Association (ABA) since 1911. Routing Numbers are used to identify your bank whenever you make a financial transaction like writing a check, setting up direct deposit, or using your bank's Bill Pay feature.
